Some of the 3D objects used in webpages and texts on this website can be shown in any Internet browser equipped with WebGL.
All 3D models can be freely rotated by pressing left mouse button and zoomed by rolling wheel button on wheel mouse. The 3D models can be moved
by pressing the middle button or wheel, or by pressing ctrl key and left mouse key. These commands are compatible with the venerable Open Inventor's
interface. All 3D models are shown entirely by HTML5 WEBGL, completely without aid of Java or Flash objects.
Available 3D models are:

Sometimes it is quite difficult to obtain WEBGL to work at all, but it is mainly attainable achievement - the main reason is strong intention
of web browsers to discard older graphic cards regardless the fact that they are fully capable to drive WEBGL subset of HTML5 even with quite decent speed.
This limitation can be surpassed by fine tuning of the web browser flags, i.e. it should be ordered to "override software rendering list"
and sometimes WEBGL should be activated too (fine tuning flags are available on chrome://flags, other browsers have different address
of flags webpage).
